Three striking features of the E3 Pure 3: It is chic, bright and light. In fact, it is one of the smallest and brightest StVZO dynamo headlights with an aluminium housing in the world. The switch-free E3 Pure 3 is a continuous light, which means that you no longer have to worry about your light - unless you manage to exceed the 100-year LED service life. This corresponds to 50,000 hours (with normal daily use). So it offers you security day and night. Only the unique Terraflux 2 lens makes it possible to combine daytime and night-time running lights in one lens. The advantage? You can do without unnecessary electronics and additional LEDs, the headlight remains minimalist and chic.
